This Answer Is A
Negative voltage regulation indicates that the load is capacitive only. This means that when the load increases, the voltage also increases. This is an undesirable condition, as it can lead to instability.
Many electric motors, capacitors, and batteries require a constant voltage to operate correctly. If the voltage changes, performance can suffer and the device can be damaged.
To prevent this from happening, it is important to ensure that the load is capacitive only and that the power factor of the load is at unity and lagging. This will keep the terminal voltage below the induced EMF and minimize voltage regulation.
